Summers in Chicago don’t just bring warmer weather—they bring plumbing headaches. Between soaring temperatures, increased water usage, and unpredictable storms, plumbing systems experience heightened stress that can lead to costly damage. These issues are particularly common in aging buildings with outdated or corroded pipes, where small weaknesses can quickly spiral into full-blown system failures.
Whether you manage a commercial facility, apartment complex, food production site, or public-use building, staying ahead of these seasonal plumbing problems is critical. Not only do summer failures pose health and safety concerns, but they also disrupt business operations, drive up maintenance costs, and erode tenant satisfaction.
Fortunately, epoxy pipelining provides a proven, trenchless solution that resolves these problems before they escalate, without tearing out walls or digging up infrastructure. Below, we’ll explore five common summer plumbing problems and how epoxy pipelining can help prevent them.
Pipe Expansion and Hidden Leaks
When temperatures spike, pipes expand, especially those made of metal like copper or galvanized steel. At first glance, this seems harmless. But over time, the constant expansion and contraction cause pipe joints to weaken, fittings to shift, and microscopic cracks to form. These tiny failures often go undetected until they lead to major water loss, interior damage, or mold growth.
This problem is especially pronounced in older buildings where the pipe infrastructure has already endured decades of seasonal stress. By summer, pipes may already be hanging on by a thread, and one more thermal cycle is all it takes to trigger a leak.
Epoxy pipelining offers a proactive solution. Instead of replacing the entire pipe system, NuFlow Midwest’s process coats the interior of the pipe with a seamless, durable epoxy lining. This barrier not only seals existing pinholes and fractures but also reinforces weakened joints, minimizing movement and preventing new leaks from forming.
Sewer Backups After Heavy Rains
Chicago summers are notorious for their intense thunderstorms. While rainfall may be welcomed by lawns and landscaping, it can be disastrous for sewer systems, especially those that are already partially obstructed, corroded, or improperly sloped. When municipal storm drains become overwhelmed, sewer water can back up into buildings, especially basements and lower-level units.
The problem worsens when interior pipes are narrow from mineral buildup or damaged by years of corrosion. Sludge, debris, and stormwater have nowhere to go, and pressure builds until it forces waste back into the building. The result? Water damage, health risks, and costly remediation work.
Epoxy pipelining addresses this by restoring the full internal diameter of sewer lines, improving flow and capacity. The epoxy coating also smooths over internal surfaces, reducing friction and minimizing the chance that debris or grease will stick and form new blockages. This is particularly valuable for food manufacturers, restaurants, and facilities with frequent drain use—any delay in service after a storm can halt operations and lead to lost revenue.
Tree Root Intrusion During Dry Spells
Summer storms aren’t the only seasonal risk—dry spells can be equally damaging. When rainfall is scarce, tree roots naturally search for underground water sources. If your plumbing system has even the smallest crack or leak, it becomes a magnet for thirsty roots.
Tree root intrusion is one of the most common causes of severe pipe damage during the summer. Roots not only penetrate pipe walls—they expand once inside, forming dense blockages that restrict water flow or cause full collapses.
Digging up root-infiltrated lines is messy, expensive, and sometimes requires removing landscaping or hardscapes. With epoxy pipelining, you can prevent this issue entirely. After cleaning out the roots and debris, the epoxy lining seals the inner surface of the pipe, eliminating entry points and forming a barrier that roots cannot penetrate. It’s a crucial investment for properties with large trees or surrounding greenery.
Clogs from High Water Demand
Summer is a high-demand season for plumbing systems. Between irrigating landscapes, running commercial kitchens, hosting more guests, and managing cooling equipment, water usage often doubles in comparison to spring or fall.
This increase in water demand puts pressure on aging pipes, especially those with internal scaling, rust, or biofilm buildup. Even if your system seemed fine in the spring, the surge in volume can expose weak spots and trigger slow drainage, foul odors, or total clogs.
Epoxy pipelining not only addresses these issues but also prevents them. After thoroughly cleaning the pipe interior using a non-toxic abrasive method, the epoxy coating smooths the walls, improving water flow and reducing the likelihood of future buildup. In many cases, flow is restored to near-original capacity, without needing to remove or replace the pipe.
Accelerated Corrosion in Aging Pipes
Heat and humidity don’t just stress your HVAC—they accelerate corrosion inside your pipes. Metal pipes such as galvanized steel, cast iron, and copper are all prone to internal rusting, which worsens in high-moisture, high-heat environments. Over time, this leads to pinhole leaks, restricted flow, discolored water, and—in extreme cases—structural pipe failure.
Unfortunately, many building owners don’t realize the speed of this deterioration until it’s too late. Replacing corroded lines is expensive, disruptive, and slow, especially in multi-unit or industrial settings.
Epoxy pipelining offers a corrosion-resistant solution that halts the decay process. Once applied, the epoxy acts as a shield between the water and the pipe wall, preventing further reaction between oxygen, minerals, and metal. This is particularly important for buildings with older plumbing systems, where full replacement is either cost-prohibitive or impractical due to access constraints.
Why Traditional Repairs Fall Short
The traditional method of addressing pipe issues—cutting out damaged sections and replacing them—comes with significant drawbacks. First, it’s time-consuming. Plumbing demolition and reconstruction can take weeks, during which tenants may need to be relocated or businesses forced to close. Second, it’s invasive. Replacing pipes often requires opening walls, ceilings, floors, and concrete slabs, causing disruption that extends far beyond the plumbing.
Lastly, it’s expensive. Once you account for the cost of demolition, labor, materials, and surface restoration (not to mention lost revenue), full pipe replacement becomes one of the most expensive repair jobs a building can face.
This is where epoxy pipelining proves its value. By using existing access points, NuFlow Midwest can restore aging or damaged plumbing systems with little to no structural disruption. Our process doesn’t require tearing out finishes, breaking through slabs, or pausing daily operations for extended periods.
Why Epoxy Pipelining Is the Better Solution
Epoxy pipelining is a trenchless technology that rehabilitates your plumbing system from the inside. Using a four-step process—inspection, cleaning, lining, and testing—we restore your pipes to full functionality while avoiding the mess and expense of traditional methods.
Here’s how it works:
Step 1: Diagnosis and Set-Up
We inspect the pipe system, make spot repairs, and remove valves. Temporary fittings and bypasses are installed. The system is drained, and pressurized air is used to check for leaks.
Step 2: Pipe Cleaning
Heated air dries the pipes, then a non-toxic abrading agent is pushed through to remove rust and buildup. All debris is collected and cleared to prepare for lining.
Step 3: Epoxy Lining
The cleaned pipe is reheated and pressure-tested. A potable water-safe epoxy is evenly applied using controlled airflow, forming a smooth, seamless inner lining. Airflow continues during the curing process.
Step 4: Reassembly and Testing
Once cured, valves are reinstalled and the system is tested for leaks, water quality, and proper flow before returning to service.
The result is a smooth, long-lasting pipe interior that resists leaks, corrosion, and buildup—and it’s ready for use in just a day or two.
